I think you're seeing the muzzle of his buddy's weapon on his left poking up into the pic.

Looks like a standard Para style rear sight. The Nigerian trooper's rifle is probably built by Imbel in Brazil, they use this style sight on their 18" Paras while the Belgians use a slightly different one.

I'm sure they are fireing on some locals that tried to sell drugs in their territory.

It would be even funnier if it was not rooted in truth. THe Nigerian "Peacekeepers" in Seira Leone blew into town and immediatly took over the cocaine trade.
